I guess my point in post #7 was that although the YM3000 in ideal condition should run a 6' cutter fine, most of these tractors that came to the U.S. to be sold are not in "new" condition, more than 30 years old and used, some of them hard use, before getting to this country. The more HP any PTO driven implement puts on these older tractors, more likely something is going to break at some point. I bought this cutter new and the shear bolt in the 5' cutter is a OEM part and has never sheared in all of the years I've run it. It's likely if there is a weak link in the drive train or the PTO drive, a larger cutter will find it sooner. Just a personal opinion.
